HEADSETS

The headset allows for a smooth, efficient fork rotation. It consists of bearings and a number of cups, washers and caps, depending on the system type (external, internal or integrated).

Key points:

· Type: headsets can be external (bearings sit onto a cup outside the head tube), internal (bearings sit onto a cup inside the head tube) or integrated (bearings sit directly onto the head tube).

· Diameter: normally, it’s standard (1 1/8”) or tapered (1 1/8” top, 1.5” bottom).
